My total ignorance of such issues is what prompted my question.
It certainly seems to be related to Cygwin to me:


   If you are using certain Cygwin builds of GCC, such as Cygwin
   version 1.1.8, you may need to specify some extra compiler flags like so:
  
     configure --with-gcc --cflags -mwin32 --cflags -D__MSVCRT__
       --ldflags -mwin32
  
   However, the latest Cygwin versions, such as 1.3.3, don't need
   those switches; you can simply use "configure --with-gcc".

Oh, I guess this `configure' actually `configure.bat', which has its
own --with-gcc option...?

Yes, although --with-gcc is the default, so it is not needed there either.

 Actually, msvc is used if it is found. If both are present,
--with-gcc is needed to force use of gcc.

So it is. I thought it was changed years ago. I have fixed that now.

But 1.3.3 is very very old and not supported any more!

The last version is 1.5.25-7 and the next will be 1.7!

Cheers,

This talks about Cygwin builds of GCC, not of Emacs.  The switches
mentioned above let Cygwin GCC produce native Windows executables (as
opposed to Cygwin executables, which depend on Cygwin runtime
support).
